Abstract

A cooking appliance can include a cooking chamber and an imaging device for capturing an image of a food item inside the chamber. The appliance can include a transparent, touchscreen display for displaying the interior contents of the cooking appliance to a user without requiring the user to open the cooking appliance, as well as providing for the user controlling, operating, and interacting with the cooking appliance.

First claim

What is claimed is:

1. A cooking appliance comprising:
a chassis defining a cooking chamber and having an access opening;
a heating element located within the chassis;
a door pivotably mounted to the chassis including a window for viewing the cooking chamber through the door, and the door being movable between a closed position to close the access opening and an opened position to open the access opening;
a transparent, touchscreen display provided on the door;
a first camera mounted to the chassis for imaging the cooking chamber interior of the chassis and configured to generate a first signal representative an image of a food item contained within the cooking chamber for display on the transparent, touchscreen display;
a second camera provided on the chassis for imaging an environment surrounding the cooking appliance and configured to determine a position and movement of a user and generate a second signal representative of the position and movement of the user; and
a controller communicatively and operably coupled to the transparent, touchscreen display, the first camera, and the second camera, and configured to receive the first signal and the second signal, and display the image of the food item contained within the cooking chamber on the transparent, touchscreen display as an augmented image of the food item that is adjustable based upon the position and movement of the user as determined by the second signal.

2. The cooking appliance of claim 1 wherein the image is adjustable by rotating the image based upon a lateral position of the user measured by the second camera.

3. The cooking appliance of claim 1 wherein the displayed image of the food item is resizable based upon a distance of the user from the door as measured by the first camera.

4. The cooking appliance of claim 1 further comprising at least one light for illuminating the transparent, touchscreen display.

5. The cooking appliance of claim 4 further comprising a gasket provided about the access opening and wherein the at least one light is provided in the gasket.

6. The cooking appliance of claim 4 wherein the door includes an inner frame and an outer frame defining a space between the inner frame and the outer frame, and the at least one light is provided in the space to illuminate the transparent, touchscreen display.

7. The cooking appliance of claim 6 further comprising a mask provided on the inner frame including at least one gap in the mask, and the at least one light is provided in the at least one gap.

8. The cooking appliance of claim 1 further comprising a user interface provided on the transparent, touchscreen display.

9. The cooking appliance of claim 8 wherein the user interface includes a transparent portion for viewing the food item within the cooking chamber through the transparent, touchscreen display.

10. The cooking appliance of claim 8 wherein the user interface further includes a control portion for operating the cooking appliance.

11. The cooking appliance of claim 10 wherein the control portion provides for coordinating the cooking of multiple food items by coordinating input times for multiple food items.

12. The cooking appliance of claim 11 wherein the user interface suggests a different position for one food item of the multiple food items to provide for imaging of the multiple food items by the first camera without visual interference of another food item by the one food item of the multiple food items as viewed by the first camera.

13. The cooking appliance of claim 1 further comprising at least one rack provided in the cooking chamber.

14. The cooking appliance of claim 13 wherein the transparent, touchscreen display suggests a different position for the rack based upon a preferred cooking position for the food item.

15. The cooking appliance of claim 13 wherein the rack and an interior of the cooking chamber are colored or coated to minimize visual interference with the transparent, touchscreen display.

16. The cooking appliance of claim 1 further comprising a probe.

17. The cooking appliance of claim 16 wherein the transparent, touchscreen display suggests a preferred position of the probe within the food item on the displayed image.

18. A cooking appliance comprising:
a chassis defining a cooking chamber and having an access opening;
a heating element located within the chassis;
a door pivotably mounted to the chassis movable between a closed position to close the access opening and an opened position to open the access opening;
a transparent, touchscreen display provided on the door;
an exterior camera provided on the chassis for imaging an environment surrounding the cooking appliance and configured to determine a position and movement of a user; and
a controller communicatively and operably coupled to the transparent, touchscreen display and the exterior camera to receive a signal from the exterior camera;
wherein an opacity of the transparent, touchscreen display is adjusted based upon the position and movement of the user such that the opacity decreases as the user moves closer to the exterior camera and the opacity increases as the user moves further from the exterior camera.

19. The cooking appliance of claim 18 further comprising a user interface provided on the transparent, touchscreen display.

20. The cooking appliance of claim 19 wherein the user interface includes a transparent portion for viewing a food item within the cooking chamber through the transparent, touchscreen display as the opacity decreases when the user moves closer to the exterior camera.

21. The cooking appliance of claim 20 wherein the user interface further includes a control portion for operating the cooking appliance that decreases opacity of the transparent, touchscreen display when the user moves closer to the exterior camera.

22. The cooking appliance of claim 18 further comprising an interior camera for imaging a food item within the cooking chamber.

23. The cooking appliance of claim 22 wherein the transparent, touchscreen display displays the imaged food item when the position of the user moves closer to the cooking appliance.
